[R-SIG-Mac] Rcpp on OSX?

[Simon Urbanek]

David,

you may want to tell the maintainer (hopefully CCed here ;)). That  
package is horribly non-portable (for no real reason) so it's not just  
a matter of setting some flags to get it to work. (Re the message you  
quoted - It's not really excluded, it simply doesn't work).

Just to get you started, *remove* src/Makefile and create the  
following src/Makevars:

all: $(SHLIB) userLibrary

USERLIB=libRcpp$(DYLIB_EXT)
USERDIR=../inst/lib

userLibrary: $(USERLIB)
	- at if test ! -e $(USERDIR)$(R_ARCH); then mkdir -p $(USERDIR)$ 
(R_ARCH); fi
	cp $(USERLIB) $(USERDIR)$(R_ARCH)
	cp Rcpp.h $(USERDIR)

$(USERLIB): Rcpp.o
	$(SHLIB_CXXLD) -o $(USERLIB) $^ $(SHLIB_CXXLDFLAGS) $(ALL_LIBS)

.PHONY: 	all clean userLibrary

clean:
		rm -f $(OBJECTS) $(SHLIB) $(USERLIB)


Cheers,
Simon
